        if ( ! $valid_attempts ) {
            set_transient( 'login_attempts', 1, 60 * 10 );
        } else {
            set_transient( 'login_attempts', $valid_attempts + 1, 60 * 10 );
        }
    }
    add_action( 'wp_login_failed', 'login_failed' );
}

if ( ! function_exists( 'login_lockout' ) ) {
    function login_lockout() {

        echo '<p>Scan the QR code below using the Google Authenticator app on your smartphone.</p>';
